Intec Pharma Announces Protocol Amendment to Phase III Study of Accordion Pill Carbidopa/Levodopa in Advanced Parkinson's Disease Patients
Sample size reduced from 460 to 328 patients without altering the trial's objectives, endpoints or statistical powering
JERUSALEM, November 7, 2016 /PRNewswire/ --
Intec Pharma Ltd. (NASDAQ: NTEC) (TASE: INTP), a clinical-stage biopharmaceutical company focused on developing drugs based on its proprietary Accordion Pill platform technology, announces that the protocol for the Accordance Study, the company's global Phase III clinical trial of the Accordion Pill Carbidopa/Levodopa (AP-CD/LD) as a treatment for Parkinson's disease (PD) symptoms in advanced PD patients, has been amended to reflect input from key opinion leaders and biostatisticians specializing in PD. The protocol amendment reduces the study's sample size from 460 patients to 328 patients, but does not alter the objectives, endpoints or statistical power (90%) of the global Phase III clinical trial. The amendment was submitted to and reviewed by the U.S. Food and Drug Administration (FDA) and the Agency had no comments to these proposed changes.
The Accordance study is a multicenter, randomized, double-blind, double-dummy, parallel, active-controlled Phase III trial in the United States, Europe and Israel. The study is now expected to enroll approximately 328 participants across the two original arms: AP-CD/LD or Sinemet® IR, an immediate release carbidopa levodopa medication that is currently on the market. The primary efficacy endpoint of the study is change from baseline to end of treatment in the percentage of daily "Off time" during waking hours.
Karl Kieburtz, M.D., President of Clintrex, consultant to the Company and Professor in the Department of Neurology at the University of Rochester and formerly Chair of the FDA Peripheral and Central Nervous System Advisory Committee commented:
"The amended protocol's sample size estimation uses a predicted standard deviation that is based on recent evidence from similar Parkinson's disease clinical trials. Using this estimated standard deviation and the same predicted difference between the active intervention and control, we achieve a substantial savings in sample size, without altering the objectives, endpoints or statistical power of the Accordance Study."
Zeev Weiss, Chief Executive Officer of Intec Pharma, said:
"Levodopa is the most effective and widely used treatment for Parkinson's disease symptoms. However, reports indicate that up to 50% of patients show onset of motor fluctuations within two years of starting conventional Levodopa therapy.
We believe that our AP-CD/LD, currently being tested in Phase III, holds huge potential in addressing a major unmet need for many Parkinson's disease patients - to improve duration and consistency of symptom relief provided by Levodopa.
We are excited to continue to advance our Phase III Accordance Study with this protocol amendment as it enables a significant reduction in sample size without altering the study's original objectives, endpoints and statistical power of 90% or eventual outcomes. We believe that the reduction in sample size should shorten study completion timelines and reduce overall costs, and we expect to complete patient enrollment in the fourth quarter of 2017.
We are committed to providing a replacement Levodopa treatment to advanced Parkinson's disease patients that experience "Off times" for hours during a typical waking day. Our goal is to improve the current treatment of this very prevalent and severe neurodegenerative disease."
